CNRS: “Global warming can lead to increased frost damage!”

Guest essay by Eric Worrall

According to Climate Scientists, Europe’s bitterly cold April would have been colder if it hadn’t been for climate change, so we must step up our effort to fight global warming.

Global Warming Is Increasing the Likelihood of Frost Damage in Vineyards

Late frosts are becoming less likely, but early growing seasons are leaving vines even more vulnerable.

By Mike Pomranz July 06, 2021

A common retort to global warming (and one of the reasons many people prefer the term “climate change”) is “If the Earth is warming, what’s up with this cold?” All intended snark aside, it’s a question scientists are genuinely interested in: Weather patterns are extremely complicated (just ask your weather app that’s never right) and determining how individual incidents tie into larger climate shifts is difficult.

For instance, this past April, France was hit with a devastating frost, affecting 80 percent of vineyards with estimated damages of around $2 billion: not the kind of outcome you’d expect from a warming planet. But new analysis from a team of European researchers suggests that this damage was ultimately tied to climate change — not because April was so cold, but because March was so warm.

“There is an apparent paradox: global warming can lead to increased frost damage!” Robert Vautard, senior scientist at the French National Centre for Scientific Research (CNRS) and director of the Institut Pierre-Simon Laplace, stated, discussing the paper he co-authored. “Our results show that climate change is making both the growing season start earlier and frosts become warmer, but the former effect dominates over the latter. The consequence is that vineyards grow and mature faster now, but this leaves them more exposed to eventual colder snaps.”

I mean there is clearly only one solution – we need to cut CO2 emissions, to ensure the return of bitterly cold Little Ice Age winters, to save French winery vineyards.

According to experts, the wine harvest in France is expected to be the weakest since 1945. The reason for this, they say, was an unusually mild March in the spring, but this was followed by a frosty April that destroyed shoots and buds in large regions of the country.
Extreme weather conditions

The French Ministry of Agriculture expects a total of 37.2 million hectoliters of production this year – 18 percent less than in 2016 and 17 percent below the average of the last five years. Already in 2016, the harvest was one of the weakest in more than 30 years. The figures from the ministry are based on assessments carried out at the beginning of August – before the harvest, which in some regions of France started two weeks earlier than usual due to weather conditions. 2017

Worst wine harvest since 1945 German

At this point, vineyards in Switzerland, large parts of France and even Italy still had the worst ahead of them. The unusually late and, in its severity for the time of year, almost unprecedented onset of frost last week caused severe problems for vintners and fruit growers in all these countries.

Although there is still no reliable balance sheet after the temporary end of the bitterly cold nights, because the damage to shoots and blossoms is only gradually becoming apparent. But in southern Styria, which was worst hit, winegrowers are already talking about

vintners are already talking about losses of between 70 percent and total. This would be a catastrophe for the small wine country of Austria, which finally needed a large harvest again. The worst was apparently the night of April 27, when temperatures dropped to minus six degrees in some places; by then, all countermeasures were of no use.
Frost damage even reported from Puglia

Similar reports are coming in from Burgundy in France: Across the growing region, even sections that normally escape frost were affected – an “extremely rare phenomenon,” as the Professional Association of Burgundy Wines (BIVB) writes. The greatest damage was apparently in Chablis, in the north of the Cote de Beaune and on the Loire. But even in the Languedoc, much further south, and even from some Italian growing areas such as Campania and Puglia, frost damage was reported 2016

Fire for the vines German

Frost damage from the spring is causing serious problems for French winegrowers. Wine production is expected to fall by around 17 percent this year, making it “historically low”.
This year’s wine harvest is also causing problems for winegrowers in France.

This was announced by the Ministry of Agriculture on Friday in a first assessment. According to the report, production is expected to fall to 37 to 38.2 million hectoliters from 45.5 million in 2016. The average value of this range would be 17 percent below last year and 16 percent below average. 2018

Reply to  markl

It is even more paradoxical when you consider the symptoms/weather of Global Warming and Global Cooling are identical:

Medieval Witch Hunts Influenced by Climate Change

“Anno 1626 the 27th of May, all the vineyards were totally destroyed by frost […], the same with the precious grain which had already flourished.[…] Everything froze, [something] which had not happened as long as one could remember, causing a big rise in price.[…] As a result, pleading and begging began among the peasants, [who] questioned why the authorities continued to tolerate the witches and sorcerers destruction of the crops. Thus the prince-bishop punished these crimes, and the persecution began in this year…”

“1445, in this year was a very strong hail and wind, as never seen before, and it did great damage, […] and so many women, which it’s said to have made the hail and the wind, were burned according to the law.”

And heat waves and droughts:

How to survive a Little Ice Age

In February 1540 rainfall effectively ceased, falling only six times in London between then and September. It was not only exceptionally dry but warm:

“This year was a hot summer and dry, so that no rain fell from June till eight days after Michaelmas [29 September], so that in divers parts of this realm the people carried their cattle six or seven miles to water them, and also much cattle died; and also there reigned strange sickness among the people in this realm, as laskes [dysentery] and hot agues, and also pestilence, whereof many people died…”

Edward Hall noted that the drought dried up wells and small rivers, while the Thames was so shallow that “saltwater flowed above London Bridge”, polluting the water supply and contributing to the dysentery and cholera, which killed people in their thousands. In Rome, no rain fell in nine months; in Paris, the Seine ran dry. Grapes withered on the vine and fruit rotted on trees. Even the small respite of autumn and winter was followed by a second warm spring and another blisteringly hot summer. Forests began to die until, in late 1541, rain fell and fell. 1542 was a year of widespread flooding.

But scientists attribute all of these to warming now. (okey dokey)

Even if global temps fell by 2 degrees in the next decade, climate scammers will just say “see, we told you! If it wasn’t for global warming it would’ve fell 2.5 degrees! We were right, now pay us more.”

This is why they changed the name to climate change. Now no matter what happens they can blame it on us. If it gets warmer it’s our fault. If it gets colder it’s our fault. If it stays the same maybe we’re off the hook. But staying the same is the one thing the climate never does.

After winter it warms up early and then it gets cold again fooling the vines or trees. I’ve been hearing orchardists and grape growers complaining about this for the last 60-70 years here in Central California. Put out smudge pots, sprinkle the leaves with water or whatever. Nearly every year the local TV news trots out a couple of growers to complain about this phenomenon (AKA the weather). Get over it everybody, it’s just Nature at work.

These extreme cold weather events are just weather, not climate. But they do raise questions. According to my local weather station just two miles down the road on a plain, in the airport fields, the air temperature barely dropped below 0 C and only for short periods just before sunrise.

There can be a large difference between ground and 6 ft up but I would walk the dog seeing cars covered in frost. This is in built up suburbs with the cars parked near houses. There was a day when it supposedly only dropped to half a degree below zero for half an hour and a couple of houses had frost on on their rooves. One was uninhabited while the other was recently renovated and must have had excellent insulation.

And as everyone knows, everywhere is warming at twice the global average.

Ulric Lyons

“The results show that while global warming made the cold wave less likely, it also made bud burst happen earlier in the year.”

The cold event was going to happen regardless of the global temperature because it was due to weak solar wind states causing negative North Atlantic Oscillation conditions. It was on my long range forecast from months back. I had also predicted the strong warm up from mid February. Climate change has diddly squat to do with any of that variability.

“The lowest temperatures between April and July have increased by 1.2ºC in the region studied due to human-caused climate change. And cold frost episodes, which would happen once every 10 years without climate change, now have a return period of approximately 160 years.”

If they could understand how solar variability drives the weather variability, they could have a much better understanding of climate change

“Our results show that climate change is making both the growing season start earlier and frosts become warmer”

The UK had the lowest mean minimum April temperatures since 1922 this April, the reality is that global warming makes no meaningful difference to cold events. December 2010 is a great example, the second coldest in over 360 years for Central England, and March 2013, like a Maunder Minimum March.

That reminds me of the molecular calculation hype. A certain phenomena was observed experimentally. Then calculations were done to find an explanation. The material was then published with the claim that the calculations predicted the phenomena which was then confirmed by actual experiment… “A posteriori” instead of “a priori“…. It’s always much easier to find reasons afterwards, than to actually foresee things…
